Figure 1 IS a side elevation of a car truck embodying the features of my invention;

Fig. 2 1s a top plan view of a portion of the truck shown in' Fi 1; Fig. 3 is a vertical transverse sectiona view taken on the line 3-3 of Fig. 1; and Fig. 4 is a view similar to Fig. 3 indicated by-the line 4-4 on Fig. 1, looking in the direction of'the arrow.

This invention relates to car trucks.

The object of my invention is to provide a passenger car truck that is strong, light and nexpensive to manufacture, and which is provided with a swing motion bolster of novel construct-ion.

'Referring to the drawings which illustrate the preferred form of iny nvention, 1 designates the side frames orwheel pieces of the truck which are preferably formed of pressed metal, said pieces being provided at their ends and upper edges with integral inwardly rojecting flanges 2. An angle 3 having its orizontal leg projecting inwardly is'secured to the lower edge portion of each of' the ,wheel pieces 1, thereby producing a built-up structure of approximately channel-shape in the transoms A, as shown in cross section, The wheel pieces or side framesl are connected together by two transoms A, and two auxiliary transoms B that are preferably formed by commercially rolled angles which are arranged parallclto Fig. 2. Each of the transoms A consists ofa pair of commercially rolled members, preferably channels 4, which are arranged with their hori- 'zontallegs or flanges projecting in opposite directions, as shown in Fig; .1, the webs of said channels being spaced apart to receive the hangers that support the spring plank as hereinafter described. Top and. :bottom cover plates 5 are secured to the flanges of channels are 'arrangedbetween the inwardly Car-Trucks, of which the 5 taken at approximately the point I projecting flanges of the side frames 1 and are secured to the vertical webs thereof by i means of angle-shaped connecting devices 6 gwhieh are preferably formed of malleable iron, each of said connecting devices being provided with a horizontal. reinforcing web 6 that connects the vertical legs thereof together, These connecting devices 6 are secured to the outside faces of the webs of the channels 4, as shown in Fig. 4, and also to the vertical legsof the angles 3 which are 1 connected to the pressed metal wheel pieces 3 1. The bottom cover plates of the transoms A terminate short of the side frames but the top cover plates project underneath t the top flanges 2 of said side frames and are secured thereto by rivets 7 which also pass through gusset plates S'interposed b-; tween said top cover plates and the inwardlf' projecting flanges of the side frames, as shown clearly in Fig. 4. The transverse angles or auxiliary transonis B have their horizontal legs secured to the gusset plates 8 and also to the top flanges 2 of the side frames 1 by rivets onother suitable fastening devices.

By building the truck in the manner above described I obtain a very rigid and strong structure withoutthe use of end pieces connecting the end portions of the side frames together, thereby producin a short truck.

The bolster C of the true is of the swin motion type and is mounted on's rings that are supported by a spring plan E, said spring plank being carried by hangers F which are pivotally supported at their upper ends in castings 10 which are supported by the transoms A ofthe truck frame. The upper ends of the hangers F are arranged between the channels of said channels will relieve the fastening devices from shearing strains. These cast tegral bearings 12 in which the fulcrum pins for the brake hangers 13 are mounted. v

The spring "plank E preferably consists of two parallel angles 14 which are connected 4 of the transomsA, as 4 shown .in Fig. 1, and the pins 9, on which.

metal bearings 10 arealso provided with in-- Fig. 4, so that the lower flanges together at the middle of the plank by cross bars or braces 15, the end portions of said angles being secured to rectangulanshap d said angles to plates 18 whichare fastened to the upper sides of the bars 16.

' The bolster C is a builtup structure which preferably consists of a pair of transverselyextending Z-ba'rs 19 arranged with their lower legs projecting outwardly and their upper legs projecting inwardly, as shown in Fig. 1. Top and bottom cover plates 20 and 21 are secured to the upper and lower legs of the 22-bars 19 and the usual center bearing 22 is mounted on the top cover plate. The central portion of the top cover plate 20 is the same width as the bottom. cover plate 21 so that it projects laterally from the vertical webs of the Z bars, the projecting portions of said top cover plate being strengthened and supported by means of angles 23 secured to the vertical webs of the Z-bars 19, as shown in Figs. 1, 2 and 3. The top cover plate 20 tapers or diminishes in width from the middle towards the ends of the bolster, as shown in Fig. 2, and adjacent the ends of the bolster side bearings 24 are secured to said. top cover plate. At the ends of the bolster short pieces 25 of angle iron are interposed between the top and bottom cover plates and are secured to the .inside faces of the vertical webs of the Z-bars 19 to form chafing irons which cooperate with chafing irons 26 secured to the inside faces of the side frames 1, as shown in Figs. 2 and 3. Chafing irons 27, which are secured to the bottom cover plate ofthe bolster C, cooperate with chafing irons 28 that are secured to the bottom cover plates of the transoms A of the truck frame. The springs D on which the bolster C rests are mounted in upper and lower spring seat 29 and 30 connected, respectively, to the bottom cover plate of the bolster and to the plates 18 on the end portions of the spring plank E, as shown in Fig. 3. The truck is also provided with safety hangers for the spring plank, said safety hangers consisting of bars 31 that are flanged at their upper ends and connected b Y fastening devices 32 to the transoms A of t 1e truck.
